Abstract

Access surveillance and anti-theft alarm device for sea or land vehicles. The present invention comprises, on a given port area or vehicle park, a device which comprises a central data-processing unit associated with at least one badge reader 3 and/or digital keyboard 2 allowing the users to enter their owner's code. The central processing unit 1.1 also receives, by microwave link 19, 12, 10, 21 an encoded signal coming from one or other of the devices mounted on vehicles, which, while moving, pass over a predetermined limit 13, 14. The correlation between the code of the ship and the code previously entered by the badge authorises the continuation of the ship's movement. Absence of recording of the owner's code results in the immediate emission of an audible 17, visual 5 and/or vocal 8, 9 alarm. The device allows the monitoring of any attempt to break in by transmitting the vehicle's code, the alarm will be triggered because of the absence of a previously entered authorisation code.

Description

 The present invention relates to a computerized control device which makes it possible to identify any maritime or land vehicle subject to movement, and to positively ensure that this movement has actually been validated by the introduction on a keyboard. or by reading a magnetic identity card of a characteristic code of the owner of said vehicle.

 Any improper use of a vehicle results in the emission of an alarm message appearing on the processing terminal of the central system; the message can take any desired visual and / or auditory, written and / or verbal form (speech synthesizer).

 The device according to the invention aims to overcome in a rigorous manner the almost impossibility of positive surveillance of each ship and / or vehicle in a given port or land area.

 To this end, the present invention relates to a device for controlling and processing identification data allowing the correlation between a vehicle and its legitimate owner and comprising in a determined area one / or more readers and / or keyboards connected by lines of specialized transmission to a central information processing unit (digital computer). The central unit will more particularly be responsible for shaping the processing (validation or not of the data received), and for archiving (chronological storage) of the codes received in real time.

 The invention comprises, on the other hand, a receiver interrogator device over the air managed by the central unit and activated by any commissioning and / or crossing of a perimeter limit for either of the vehicles under control, and on the other hand, comprises on each ship or vehicle a responder device activated by the interrogation signal from the central port unit.

 The ship's response signal is characteristic of this and contains in coded form all the elements allowing the central unit to identify it.

 Any negative response to the search for correlation between ship code and owner code resulting in the issuance of an alarm message. A positive response being either ignored or used for further processing (situation at a given moment of the movements of a fleet of vehicles or ships).

The accompanying drawings illustrate the invention
Figure 1 show the diagram of the central device
fixed according to the invention.

FIG. 2 represents the diagram of the device intended for
equip the maritime or land mobile according to the invention.

The device shown in FIG. 1 comprises a central computer processing unit (1) ensuring all of the management of the device. This unit is interfaced with keyboards (2) and / or magnetic badge readers (3) which are distributed over a
area according to the reassurance points of the users (vehicle owners), the link between the readers and the central unit being by serial transmission lines (4).

 The operator responsible for the device has a dialogue terminal (5) (screen / keyboard) with the central unit, as well as the usual management means, printer (15), mass memory (6) (magnetic recorder with discs) and a telephone message transmission interface equipped with a program synthesizer (8) and a 1ODEM (9) authorizing access to the national telephone network.

 The central unit also manages a badge encoder (7) allowing the preparation and / or exchange of user badges in the event of loss or theft.

 The device further comprises a central transmitter / receiver assembly (10.11.12), connected to a common antenna (19) by means of a diplexer (12) ensuring the separation and isolation of the two transmit / receive signals. who can other simultaneous. The conventional type transmitter (11) is activated by information originating either from a photoelectric barrier (13) or from a Doppler radar (14).

 The photoelectric barrier (13) and / or Doppler radar (14) reacting to the passage and / or crossing a limit by a mobile of predefined volume (height of the light beam or sensitivity of the radar).

 Coming from the encoder (20) the modulating signal of the transmitter is a burst of five low frequency tones (according to the standard in force in the user country ?. This signal constitutes a telephone number composed of five digits, which characterizes a port or a defined site.

 The call return from a mobile (boat or land vehicle) is received by an amplification and filtering receiving device (10) associated with a decoder (21) restoring at its output a succession of binary elements containing the five call return digits (port code). This call return is followed sequentially by a similar code characteristic of the mobile in question. This binary information from the decoder (21) is transmitted to the central unit (1).

 When a message is received, the central unit checks, - firstly, the identity of the code of the responding ship. To do this, the central unit performs a search in "database1, (mass memory) of an identical code, previously recorded when the mobile is taken into account by the port authority or sector directorate.

 Secondly, the central unit searches in memory for a movement authorization code introduced by reading a badge (title deed) on one or other of the readers (3) already mentioned. , in order to facilitate the use of the system by people in bathing suits. It is possible to use a keyboard (2) on which the owner of a boat can manually enter his personal code instead of the badge.

 In the event of reception of a message presenting a complete validation (correlation between ship code and movement code), the central unit will carry out its archiving (memorization taking into account the date and time) for deferred use (management, statistics, port movement study, etc ...).

 If a boat code is received without a movement authorization code, the central unit immediately publishes a clear text on the terminal screen (5) and / or accompanied by a audible signal (17) (alert) with, depending on the time or the season, the sending of a telephone message (8.9) to the home of the owner or his principal.

 The telephone codes are prerecorded in the database when the ship or vehicle is taken into account in the device according to the invention.

 The device shown in fig. 2 intended to be installed on a maritime or land mobile is contained in a sealed enclosure and sheet (11) made of molded metal that can withstand both climatic stresses and attempts to break and enter.

 The device is mechanically fixed to the structure of the mobile in such a way that its removal requires a long intervention (number of foci) and complex (specialized tools).

 The device further comprises an internal energy source by rechargeable battery (9), powered by a panel of photovoltaic batteries (solar cells) (10). The autonomy of the device's battery pack is sufficient to allow the device to operate during night periods.

 The electrical power of the photovoltaic panel (10) is sufficient to allow the device to work and to recharge the battery pack during the most unfavorable daytime period.

The device further comprises a receiver (3) connected to an external antenna (1). This conventional receiver with selective amplification receives the high frequency signal from the transmitter of the port unit described above in the device (fig.l
The demodulated signal from the receiver (3) is routed on an analyzer circuit (4) responsible for recognizing the five-tone burst and developing the corresponding number (five digits).

 This numerical code is characteristic of the home port of the mobile. I1 is applied to the central unit (5) responsible for identifying the calling code by comparison with a code pre-programmed by wiring or coding wheel (6).

 If the troop code is correct, the central unit will ensure the activation of the transmitter module (7) and its modulation by the automatic sequence of the N1 call and ship identification N2 sequences.

 The device activation automations (fig. 2) are supported var a proFXrammable automaton (8) connected to break-in sensors (12) (compartment, engine, panels, hatch, door, etc ...) at a security key (13) used to neutralize the action of the sensors (12).

 In the event of a break-in, the activation of the device is immediate and causes the emission of the vehicle code. This code is not associated with an authorization code from a badge reader.

The central device triggers an alarm as described above.

 Of course, the present invention is not limited to the embodiment described and also includes any modification OR modification that may be made by those skilled in the art.

 The choice of frequency and power will obviously have to take into account the regulatory requirements of a given territory and the technical constraints for a specific application.

 The module installed on vehicles is contained in a metal casing (fig. 2.11) impervious to salt spray and is tamper-proof fixing with standard tools (use of screws with special imprint).

 The transmission and reception means include coding and decoding circuits (fig. 2.4 and 2.5) (fig. 1.20 and 1.21) provided by specialized integrated circuits (micro-controller) and their associated software.

 The identification codes used by coders / decoders (fi -. 1.20, 1.21) and (fig.2. 4,5,6) are successions of low frequency bursts representing a sequence of five digits, each digit of O to 9 being represented by a characteristic frequency 3F, the definition of which is subject to international standardization (CCIR).

 The module (fig. 2) on the vehicle is arranged to be able to be activated directly by the entry into action of one or more break-in sensors (fiv.2.12) placed in any location desirable for the safety of said vehicle. These sensors are well known to those skilled in the art such as a flexible blade switch, shock detector, accelerometer, infrared detector, etc. This list is not exhaustive. The sensors (fig.2. 12!
